Challenge Going Forward

• Project close-out - YBITS1 & OTD2 (Near Term) & SAS• Environmental Risks Continue to Increase Based on Communication

with National and State Agencies• Some opportunities for cost mitigation include:

1. Eliminate the risk related to cost estimate uncertainty of 504/288 and Marine Foundations contracts if bids come in under the estimates.

2. Obtain Concurrence to Leave Foundations – E2 & E19-E22

Memorandum

TO: Toll Bridge Program Oversight Committee (TBPOC)

DATE: October 28, 2014

FR: Brian Maroney, Deputy Program Manager, Caltrans Mike Whiteside, Structure Specifications Manager, Caltrans Ken Brown, Chief Structures Maintenance – Toll Bridges, Caltrans

RE: Agenda No. - 5b Item- San Francisco-Oakland Bay Bridge (SFOBB) Updates

Bridge Information Model (BrIM) DB Pilot Program Update

Recommendation: APPROVAL Staff is requesting that the TBPOC approve/ endorse the attached BRIM Pilot Program proposal for submittal to the BATA/ Caltrans Rehab Program for potential funding and implementation. Cost Impact: N/A Schedule Impact: N/A Discussion: At the March 13, 2014 TBPOC meeting, Brian Maroney and Mike Whiteside presented a proposal for the development of a pilot project for BrIM Database for the SFOBB Corridor. The TBPOC expressed interest in the proposal and requested additional clarification regarding potential cost advantages of using a BrIM database on bridge lifecycle maintenance and rehabilitation costs. An estimate has been developed for the purposes of this proposal to evaluate costs for future maintenance and rehabilitation of the New East Spans for its 150 year design life with and without a BrIM database. The use of a BrIM database for the lifecycle maintenance and rehabilitation of the New East Spans will result in a net cost advantage of $300M - $350M in 2014 dollars. It is strongly recommended that a pilot project for a BrIM Database for the SFOBB New East Spans be implemented on an immediate basis. Time is of the essence. A delay in the development of BrIM Database for this lifeline bridge would only increase

the risk of loss of valuable design and construction information that may have to be regenerated in the future at significant additional costs, if even possible. Immediate implementation of the pilot project will allow for the consolidation and preservation of design and construction information for the SFOBB New East Spans that history has shown to be vulnerable to loss.

It is further recommended that a special purpose 3D BrIM database (BrIM Database) be developed as the pilot project for the SFOBB New East Spans. The BrIM model for this database will capture the entire New East Spans in complete as-built geometry with block level detail for all concrete and steel components. All structural elements of the New East Spans that are designed to take damage and are expected to require repairs after a design level earthquake will be modeled in complete as-built detail. A database for design drawings, structural & strength properties, and as-built shop drawings for the aforementioned elements of the New East Spans will be integrated into the BrIM model.

The schedule for completion of this effort is 24 months. A funding of $10M is hereby requested from the BATA Toll Bridge Rehabilitation funds for the BrIM Database pilot project for the SFOBB New East Spans with an allocation of $5M per year. An oversight group comprising of BATA and Caltrans representatives will be assigned to guide and evaluate the progress of this program every three months. As an option, this project may be extended to include the SFOBB West Spans in order to provide a comprehensive BrIM Database for the entire SFOBB Corridor. The TBPOC is hereby requested to provide its support and endorsement to the proposed BrIM Database pilot project. Attachment(s): NA
